SAM CORTESE, OF DUNSMUIR, CALIFORNIA.

SEWING AWL FOR LEATHER GOODS.

Original application filed March 1, 1922, Serial'No. 540,239. Divided and this application filed August 3, 1923. Serial No. 655,429.

T all whom it may concern:

Be it known that I, SAM Con'rnon, a citizen of the United States, residing at Dunsmuir, in the county of Siskiyou and State of Cali.- fornia, have invented certain new and useful Improvements in Sewing Awls for Leather Goods, of which'the following is a specification.

This is a divisional application of my application Serial No. 540,239, filed March 1, 1922, for which Patent, No. 1,468,698, was granted September 25, 1923.

The invention relates to awls intended for use in connection with the handle described in said patent and has a principal use in sewing leather goods by hands. It is thus possible not only to do the actual sewing or stitching but also to pierce the goods to be sewn at the same time, so that no other implements are necessary for the latter operation. For this purpose the further object of the invention is to provide twin needles, one longer than the other, the shorter one being placed in advance of the longer one in order to pierce a hole for the latter, which simultaneously is made to pass through the previously made hole and to return with the thread from the upper side of the work. As the two needles always pass together through the layers of leather, the spacing of the stitches becomes uniform throughout, so that the stitching will have the appearance of machine stitching, being just as uniform as the latter.

In the accompanying drawing,

Figure 1 represents a perspective View of the twin needle inserted in its handle;

Figure 2 is a perspective view of a pair of straight needles;

Figure 3 is a similar viewof a pair of bent needles similar to the ones shown in Figure 1;

Figure 4 is also a perspective view of a pair of bent needles slightly longer than the ones. indicated in Figure 3; and

Figure 5 is a pair of bent needles separated from each other.

In the drawing, reference numeral rep resents a handle suitable for the twin needles and provided with a socket 11 into which the twin needles 12 fit and being secured thereiniby means of a set screw 13.

The preferred construction of the needles is shown in Figures 3 and 4, that is to say, bent twin needles. These are joined together in a common stem 14 which fits in a socket provided in the handle 10. From this stem 14 extends upwardly, the sewing needle or prong 15 which terminates with a sharp point having a rearwardly directed hook 16. The other prong 17 is considerably shorter but bent parallel to the long prong 15. This second prong terminates witha sharp point 18 and serves as an awl to pierce the holes for the prong or sewing needle 15. The only difference between the construction illustrated in Figure 3 and that shown in Figure 4 is that the latter has longer prongs 19 and 20 and that the curving of the same starts directly above the stem 14, while the needle shown in Figure 3 has, first, a straight lower portion of the prongs, which at the upper ends thereof turn into a curved portion. These two constructions are best used by shoemakers.

Sometimes it might be advisable to make the two needles separate as shown in Figure 5, where the awl 21 is, as before, shorter than the sewing needle 22. These needles have individual stems 23 and 24 which may fit into a single socket provided in the handle 10, or in twin sockets if preferable. The straight twin needle shown in Figure 2 is intended for use on saddlery or harness work. This twin needle has also a common stem 25, from which rise the two straight prongs 26 and 27, the former terminatlng with a sharp point and being shorter than the latter, and is intended for use as an awl, while the longer prong 27 terminates with a sharp point 28 having a back turned hook 29. As before, these straight prongs are parallel with each other and the awl is set ahead of the needle 27 to pierce a hole in ad- Vance when the needle performs the stitching. It will be evident that even in this case, the spacing of the holes will be uniform and just as even as in machine sewing.

The use of the twin needles is as follows After the work 30 has been secured on a suitable bench and a spool carrying a thread 31 arranged adjacent thereto and the twin needle secured in the socket in the handle 10 by means of a set screw 13, the operator grasps the handle in one hand, the needle 12 pointing in the direction of the work. For the first stitch, the awl or prong 17 is pushed through the layers of the work piercin it and thereupon the long rong 15 is pus red through the hole provi ed, while simultathrough the work, its hook 16 engagesaround the upper threadfil whereupon the tool is retracted with the thread around the hook 16, when the long prong or needle 15 will draw the upper thread through the Work, as seen in Figure 1, forming a loop in the thread. Another thread 32 emitting from the side slit in the handle 10 is carried by a-spool revolubly mountedtherein. The end of this thread 32- is secured in'the work '30 and a long'zloop, six or seven inches in length, is nowforined on the upper thread '31 'whichis made to lock with the under thread 32, whereupon the two threads are drawn tightly to form .a stitch in the work. This operation is thereupon repeated and for the next stitch, the long needle or prong 15 passes through the opening previously pierced by the short prong or awl 17, while the latter simultaneously pierces another hole in advance of the one in whichthe needle l5 operates.

Having thus described the invention, what is claimed as new is:

1. A twin needle having a long and a short prong parallel and curved in the same direction, the short prong constituting an awl and the long prong terminating with a hook, and a broad flat stem uniting the prongs and adapted to be secured in a suitable handle.

2. 'The combination with a handle having 'a socket and a set screw, of a twin needle havinga long and a short prong parallel and curved in the same direction the short prong constituting an awl and the long prong terminating with a h0ok,and a broad flat stein uniting the prongs, said socket being adapted to receive the'stem and the set screw to firmly lock the stem in position.

In testimony whereof I'a-fiiX my signature.
